    Possible causes and solutions: Ground Fault Detect enabled The control panel has a ground fault detection circuit that when enabled, detects ground faults on Terminals 1 to 9 and 11 to 30. If a ground fault condition occurs, the keypads annunciate a ground fault and control panel transmits a trouble message. Ground Fault condition is corrected When the control panel recognizes that the ground fault condition is corrected, and remains corrected for between 5 to 45 consecutive seconds, the control panel clears the fault from the keypad display and sends a restoral report   Measure earth ground (Terminal 10) and COMMON (Terminal 9) to determine whether the control panel has the necessary 0 VDC decay to -2.1 VDC. Measuring and comparing voltage for ground fault detection: Set your digital voltmeter (DVM) to measure VDC. Connect the red DVM lead to control panel Terminal 10, and the black DVM lead to Terminal 9. Compare this voltage to the following table: Enable Ground Fault Detect and reports To enable fault detection, use RPS. Set the following parameters: ·        PANEL WIDE PARAMETERS > Miscellaneous > Ground Fault Detection. Set to Enable ·        PANEL WIDE PARAMETERS > Report Routing > Burglar Reports > Trouble Report. Set to Yes. ·       PANEL WIDE PARAMETERS > Report Routing > Burglar Reports > Burg Restore (After Trouble). Set to Yes.

    Causes: The heartbeat LED on the B426 is off. No communication failure, trouble or communication module missing error messages at the keypad. Solution Check the TMPR pins next to the Ethernet port on the B426.   Remove the jumper from the pins; the B426s heartbeat LED will start flashing to show the firmware version on the board and then it will resume normal or trouble operation depending on the condition on the B426. When the Tamper jumper is covering both pins the heartbeat LED is turned off to save power.

      Cause: When the B420 or B426 has been programmed through the web interface and the setting; Panel Programming Enable has been set to NO, the B420 or B426 Ethernet Communicator module programming screen will look as displayed below with programming parameters not available for changing.   Solution: The card will need to be accessed again through the web interface and Panel Programming Enable must be changed to read YES. Log into the Web-Browser and select Maintenance. Click on the drop-down arrow beside the field; Panel Programming Enable  and change it to Yes. When programming the B420 or B426 to be connected to a GV3 or older panel the web interface is used. When programming the B420 or B426 to be connected to a GV4 panel, use keypad programming.
